("Parent"), proposes to sell to you (the "Underwriter") an aggregate of
9,500,000 shares (the "Firm Shares") of the common stock of ONEOK, Inc., an
Oklahoma corporation (the "Company"), par value $0.01 per share, together with
each associated preferred stock purchase right under the Amended and Restated
Rights Agreement, dated as of February 5, 2003 (the "Rights Agreement"), between
the Company and UMB Bank, N.A., as Rights Agent (the "Common Stock"). The
Selling Stockholder and, to the extent the Selling Stockholder transfers its
shares of Common Stock to Parent prior to the Option Closing Date (as
hereinafter defined) in accordance with the Stipulation and Agreement of the
Kansas Corporation Commission, Parent, have also agreed to grant to the
Underwriter an option (the "Option") to purchase up to an additional 1,425,000
shares (the "Option Shares") of Common Stock on the terms and for the purposes
set forth in Section 1(b). The Firm Shares and the Option Shares are herein
referred to as the "Shares".

     The initial public offering price per share for the Shares and the purchase
price per share for the Shares to be paid by you shall be agreed upon by the
Company, Parent, the Selling Stockholder and the Underwriter, and such agreement
shall be set forth in a separate written instrument substantially in the form of
Exhibit A hereto (the "Price Determination Agreement"). The Price Determination
Agreement may take the form of an exchange of any standard form of written
telecommunication among the Company, Parent, the Selling Stockholder and the
Underwriter and shall specify such applicable information as is indicated in
Exhibit A hereto. The offering of the Shares will be governed by this Agreement,
as supplemented by the Price Determination Agreement. From and after the date of
the execution and delivery of the Price Determination Agreement, this Agreement
shall be deemed to incorporate, and, unless the context otherwise indicates, all
references contained herein to "this Agreement" and to the phrase "herein" shall
be deemed to include the Price Determination Agreement.



     Each of the Company, Parent and the Selling Stockholder confirms as follows
its agreements with the Underwriter.

1.   Agreement to Sell and Purchase.

     (a)  On the basis of the representations, warranties and agreements of the
          Company, Parent and the Selling Stockholder herein contained and
          subject to all the terms and conditions of this Agreement, the Selling
          Stockholder agrees to sell to you and you agree to purchase from the

          Company in accordance with subsection (c) below and set forth in the
          Price Determination Agreement 9,500,000 Firm Shares as set forth on
          Schedule I.

     (b)  Subject to all the terms and conditions of this Agreement, the Selling
          Stockholder and, if applicable, Parent, grant to you the Option to
          purchase up to 1,425,000 Option Shares from the Selling Stockholder or
          Parent, as the case may be, at the same price per share as you will
          pay for the Firm Shares. The Option may be exercised only to cover
          over-allotments in your sale of the Firm Shares and may be exercised
          in whole or in part at any time (but not more than once) on or before
          the 30th day after the date of this Agreement, upon written or
          telegraphic notice (the "Option Shares Notice") by the Selling

          (the "Option Closing Date") setting forth the aggregate number of
          Option Shares to be purchased and the time and date for such purchase.
          On the Option Closing Date, the Selling Stockholder or Parent, as the
          case may be, will sell to you the number of Option Shares set forth in
          the Option Shares Notice and you will purchase such Option Shares.

     (c)  The initial public offering price per share for the Firm Shares and
          the purchase price per share for the Firm Shares to be paid by the
          Underwriter shall be agreed upon and set forth in the Price
          Determination Agreement.

2.   Delivery and Payment.

     (a)  Delivery of the Firm Shares shall be made to you against payment of

          Such payment shall be made at 10:00 a.m., New York City time, on the
          third business day after the date on which the first bona fide
          offering of the Firm Shares to the public is made by you or at such
          time on such other date, not later than ten business days after such
          first offering date, as may be agreed upon by the Company, Parent, the
          Selling Stockholder and the Underwriter (such date is hereinafter
          referred to as the "Closing Date"). Delivery of the Firm Shares shall
          be made through the facilities of The Depository Trust Company unless
          you shall otherwise instruct.

                                       2

          against payment by you (in the manner specified above) will take place

          Closing Date.

     (c)  Certificates evidencing the Shares shall be in definitive form and

          issuance and delivery of the Firm Shares and Option Shares by Parent
          or the Selling Stockholder to the Underwriter shall be borne by Parent
          and the Selling Stockholder. Parent and the Selling Stockholder will
          pay and save the Underwriter and any subsequent holder of the Shares
          harmless from any and all liabilities with respect to or resulting
          from any failure or delay in paying federal and state stamp and other
          transfer taxes, if any, which may be payable or determined to be

          places as the Underwriter shall request.

3.   Representations and Warranties of the Company. The Company represents,
     warrants and covenants to the Underwriter, Parent and the Selling
     Stockholder that:

     (a)  The Company meets the requirements for use of Form S-3 and a
          registration statement (Registration No. 333-104318) on Form S-3
          relating to the Shares, including a preliminary prospectus and such
          amendments to such registration statement as may have been required to
          the date of this Agreement, has been prepared by the Company under the
          provisions of the Securities Act of 1933 (the "Act"), and the rules
          and regulations (collectively referred to as the "Rules and
          Regulations") of the Securities and Exchange Commission (the

          prospectus as contemplated by Rule 430 or Rule 430A ("Rule 430A") of
          the Rules and Regulations included at any time as part of the
          registration statement. Copies of such registration statement and
          amendments and of each related preliminary prospectus have been
          delivered to the Underwriter. The term "Registration Statement" means
          the registration statement described above, as amended at the time it
          became effective (the "Effective Date"), including financial
          statements and

                                       3



          all exhibits and any information deemed to be included by Rule 430A or
          Rule 434 of the Rules and Regulations. If the Company files a
          registration statement to register a portion of the Shares and relies
          on Rule 462(b) of the Rules and Regulations for such registration
          statement to become effective upon filing with the Commission (the
          "Rule 462 Registration Statement"), then any reference to the
          "Registration Statement" shall be deemed to include the Rule 462
          Registration Statement, as amended from time to time. The Company will
          file with the Commission a prospectus supplement (the "Prospectus
          Supplement") relating to the Shares pursuant to Rule 424 or Rule 434
          under the Act. The term "Prospectus" means the form of final
          prospectus included in the Registration Statement at the Effective

          to include the "electronic Prospectus" provided for use in connection
          with the offering of the Shares as contemplated by Section 5(j) of
          this Agreement. Any reference herein to the Registration Statement,
          any preliminary prospectus or the Prospectus shall be deemed to refer
          to and include (i) the documents incorporated by reference therein
          pursuant to Item 12 of Form S-3 that were filed under the Securities
          Exchange Act of 1934 (the "Exchange Act"), on or before the Effective
          Date or the date of such preliminary prospectus or the Prospectus, as
          the case may be, and (ii) any copy thereof filed with the Commission
          pursuant to its Electronic Data Gathering, Analysis and Retrieval
          System ("EDGAR"). Any reference herein to the terms "amend,"
          "amendment" or "supplement" with respect to the Registration
          Statement, any preliminary prospectus or the Prospectus shall be
          deemed to refer to and include the filing of any document under the
          Exchange Act after the Effective Date, or the date of any preliminary
          prospectus or the Prospectus, as the case may be, and deemed to be
          incorporated therein by reference.

     (b)  The Company has not received, and has no notice of, any order of the
          Commission preventing or suspending the use of any preliminary
          prospectus, or instituting proceedings for that purpose. Each
          preliminary prospectus and the Prospectus when filed complied in all
          material respects with the Act and, if filed by electronic
          transmission pursuant to EDGAR (except as may be permitted by
          Regulation S-T under the Act), was identical to the copy thereof
          delivered to you for use in connection with the offer and sale of the
          Shares. On the Effective Date, the date the Prospectus is first filed
          with the Commission pursuant to Rule 424(b) of the Rules and
          Regulations, at all times subsequent to and including the Closing Date
          and when any post-effective amendment to the Registration Statement
          becomes effective or any amendment or supplement to the Prospectus is
          filed with the Commission, the Registration Statement and the
          Prospectus (as amended or as supplemented if the Company shall have
          filed with the Commission any amendment or supplement thereto),
          including the financial statements included or incorporated by
          reference in the Prospectus, did or will comply with all applicable
          provisions of the Act, the Exchange Act, the rules and regulations
          thereunder (the "Exchange Act Rules and Regulations") and the Rules
          and Regulations and will contain all statements required to be stated
          therein in accordance with the Act, the Exchange Act, the Exchange Act
          Rules and Regulations and the Rules and

                                       4



          Regulations. On the Effective Date and when any post-effective
          amendment to the Registration Statement becomes effective, no part of
          the Registration Statement or any such amendment did or will contain
          any untrue statement of a material fact or omit to state a material
          fact required to be stated therein or necessary in order to make the
          statements therein not misleading. At the Effective Date, the date the
          Prospectus or any amendment or supplement to the Prospectus is filed
          with the Commission and at the Closing Date and, if later, the Option
          Closing Date, the Prospectus did not and will not contain any untrue
          statement of a material fact or omit to state a material fact
          necessary to make the statements therein, in the light of the
          circumstances under which they were made, not misleading. The
          foregoing representations and warranties in this subsection (b) do not
          apply to any statements or omissions made in reliance on and in
          conformity with information relating to the Underwriter furnished in
          writing to the Company by the Underwriter specifically for inclusion
          in the Registration Statement or Prospectus or any amendment or
          supplement thereto. For all purposes of this Agreement, the concession
          and reallowance figures appearing in the fifth paragraph under the
          caption "Underwriting" and the information contained in the thirteenth
          and fourteenth paragraphs under the caption "Underwriting" in the
          Prospectus constitute the only information relating to the Underwriter
          furnished in writing to the Company specifically for inclusion in the
          Registration Statement or the Prospectus. The Company has not
          distributed any offering material in connection with the offering or
          sale of the Shares other than the Registration Statement, the
          preliminary prospectus, the Prospectus or any other materials, if any,
          permitted by the Act.

     (c)  The documents that are incorporated by reference in the Prospectus or
          from which information is so incorporated by reference, when they
          became effective or were filed with the Commission, as the case may
          be, complied in all material respects with the requirements of the Act
          or the Exchange Act, as applicable, the Exchange Act Rules and
          Regulations and the Rules and Regulations; and any documents so filed
          and incorporated by reference subsequent to the date hereof shall,
          when they are filed with the Commission, conform in all material
          respects with the requirements of the Act and the Exchange Act, as
          applicable, the Exchange Act Rules and Regulations and the Rules and
          Regulations.

     (d)  The only subsidiaries (as defined in the Rules and Regulations) of the
          Company are the subsidiaries named on Schedule II hereto (the
          "Subsidiaries"). The Company and each of its Subsidiaries is, and at
          the Closing Date will be, a corporation, limited liability company,
          general partnership or limited partnership duly organized, validly
          existing and in good standing under the laws of its jurisdiction of
          incorporation or organization. The Company and each of its
          Subsidiaries have, and at the Closing Date will have, full power and
          authority to conduct all the activities conducted by it, to own or
          lease all the assets owned or leased by it and to conduct its business
          as described in the Registration Statement and the Prospectus. The
          Company and each of its Subsidiaries is, and at the Closing Date will
          be, duly licensed or qualified to do business and in good

          standing as a foreign corporation, limited liability company, general
          partnership or limited partnership in all jurisdictions in which the
          nature of the activities conducted by it or the character of the
          assets owned or leased by it makes such licensing or qualification
          necessary, except to the extent that the failure to so qualify or be
          in good standing would not have a material adverse effect on the
          condition (financial or otherwise), earnings, cash flow, business
          affairs or business prospects of the Company and its Subsidiaries,
          considered as one enterprise (a "Material Adverse Effect"). Except as
          set forth on Schedule II hereto, all of the outstanding shares of
          capital stock, capital interests or partnership interests of the
          Subsidiaries have been duly authorized and validly issued and, as to
          capital stock, are fully paid and non-assessable, and are owned by the
          Company free and clear of all security interests, liens, encumbrances
          and claims whatsoever. Except for (i) the stock of or interests in the
          Subsidiaries disclosed on Schedule II hereto and (ii) as disclosed in
          the Registration Statement and the Prospectus, the Company does not
          own, and at the Closing Date will not own, directly or indirectly, any
          shares of stock or any other equity or long-term debt securities of
          any corporation or have any equity interest in any firm, partnership,
          joint venture, association or other entity. Complete and correct
          copies of the certificate of incorporation and of the by-laws or other
          organizational documents of the Company and each of its significant
          subsidiaries (as defined in Rule 1-02(w) of Regulation S-X of the
          Rules and Regulations) and all amendments thereto have been delivered
          to you, and no changes therein will be made subsequent to the date
          hereof and prior to the Closing Date or, if later, the Option Closing
          Date.

     (e)  None of the Subsidiaries is currently prohibited, directly or
          indirectly, from paying any dividends to the Company, from making any
          other distribution on such Subsidiary's capital stock, from repaying
          to the Company any loans or advances to such Subsidiary from the
          Company or from transferring any of such Subsidiary's property or
          assets to the Company or any other Subsidiary, except as described or
          contemplated by the Registration Statement and the Prospectus.

     (f)  The outstanding shares of Common Stock (including shares of Common
          Stock issuable upon conversion of the Company's $0.925 Series D
          Non-Cumulative Convertible Preferred Stock, par value $.01 per share
          (the "Series D Preferred Stock")) have been duly authorized, validly
          issued, fully paid and nonassessable and will not be subject to any
          preemptive or similar right. The description of the Common Stock in
          the Registration Statement and the Prospectus is, and at the Closing
          Date and the Option Closing Date, as applicable, will be, complete and
          accurate in all respects. Except (i) as set forth in the Registration
          Statement and the Prospectus and (ii) with respect to (A) stock
          options or other employee and director compensation arrangements
          pursuant to the terms of a plan in effect on the date of this
          Agreement or (B) employee thrift plans or direct stock purchase or
          dividend investment plans in place on the date of this Agreement, the
          Company does not have outstanding, and at the Closing Date and the
          Option Closing Date, as applicable, will not have outstanding, any
          options to purchase, or any rights or warrants to subscribe for, or
          any securities or


                                       6



          obligations convertible into, or any contracts or commitments to issue
          or sell, any shares of Common Stock, any shares of capital stock of
          any Subsidiary or any such warrants, convertible securities or
          obligations.

     (g)  The financial statements and schedules included or incorporated by
          reference in the Registration Statement or the Prospectus, and any
          amendment or supplement thereto, present fairly the consolidated
          financial condition of the Company, as of the date thereof and the
          consolidated results of operations and cash flows of the Company for
          the period covered thereby, in conformity with generally accepted
          accounting principles applied on a consistent basis throughout the
          entire period involved. KPMG LLP (the "Accountant"), the accounting
          firm that has certified the financial statements and schedules
          included or incorporated by reference in the Registration Statement or
          the Prospectus, and any amendment or supplement thereto, is an
          independent public accounting firm within the meaning of the Act and
          the Rules and Regulations and the Accountant is not in violation of
          the auditor independence requirements of Section 201 of the
          Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act") with respect to
          the Company. There are no pro forma financial statements or other pro
          forma financial information required to be included or incorporated by
          reference in the Registration Statement or the Prospectus. No other
          financial statements or schedules of the Company are required by the
          Act, the Exchange Act or the Rules and Regulations to be included or
          incorporated by reference in the Registration Statement or the
          Prospectus. The financial data set forth in the Prospectus under the
          captions "Summary -- Summary Consolidated Financial Data" and
          "Capitalization" fairly present the information set forth therein on a
          basis consistent with that of the audited financial statements
          incorporated by reference in the Registration Statement. The Company's
          ratio of earnings to combined fixed charges and preferred stock
          dividend requirements set forth in the Prospectus under the caption
          "Ratio of Earnings to Combined Fixed Charges and Preferred Stock
          Dividend Requirements" and in Exhibit 12.1 to the Registration
          Statement have been calculated in compliance with Item 503(d) of
          Regulation S-K under the Act.

     (h)  The books, records and accounts of the Company and its Subsidiaries
          accurately and fairly reflect, in reasonable detail, the transactions
          in and dispositions of the assets of the Company and its Subsidiaries.
          The Company and each of its Subsidiaries maintain an adequate internal
          control structure, procedures for financial reporting and a system of
          internal accounting control sufficient to provide reasonable assurance
          that (i) transactions are executed in accordance with management's
          general or specific authorization; (ii) transactions are recorded as
          necessary to permit the preparation of the Company's consolidated
          financial statements in conformity with generally accepted accounting
          principles and to maintain accountability for the assets of the
          Company and its Subsidiaries; (iii) access to the assets of the
          Company and its Subsidiaries is permitted only in accordance with
          management's general or specific authorization; and (iv) the recorded

          all laws, regulations and orders applicable to it or its business,
          including the Sarbanes-Oxley Act, other than noncompliance that would

          by-laws or other organizational documents.

     (m)  No consent, approval, authorization or order of, or any filing or
          declaration with, any court or governmental agency or body is required
          to be obtained by the Company in connection with the issuance of
          shares of Common Stock upon conversion of shares of Series D Preferred
          Stock by the Selling Stockholder, in connection with the transfer,

     (n)  The Company has full corporate power and authority to enter into this
          Agreement and the Transaction Agreement dated as of August 4, 2003
          among the Company, Parent and the Selling Stockholder (the
          "Transaction Agreement") and to perform its obligations under this
          Agreement and the Transaction Agreement. This Agreement and the
          Transaction Agreement have been duly authorized, executed and
          delivered by the Company and constitute legal, valid and binding
          obligations of the Company, enforceable against the Company in
          accordance with the terms hereof and thereof, subject to the effect of
          bankruptcy, insolvency, reorganization, receivership, moratorium and
          other laws affecting the rights and remedies of creditors generally
          and general equitable principles and subject to any principles of
          public policy limiting the rights to enforce any indemnification
          provisions contained herein and therein. The performance of this
          Agreement and the Transaction Agreement and the consummation of the
          transactions contemplated hereby and thereby and the application of
          the net proceeds from the offering and sale of the Shares in the
          manner set forth in the Prospectus under "Use of Proceeds" will not
          result in the creation or imposition of any lien, charge or
          encumbrance upon any of the assets of the Company or any of its
          Subsidiaries pursuant to the terms or provisions of, or result in a
          breach or violation of any of the terms or provisions of, or
          constitute a default under, or give any other party a right to
          terminate any of its obligations under, or result in the acceleration
          of any obligation under, the certificate of incorporation or by-laws
          of the Company or any of its Subsidiaries, any material contract or
          other agreement to which the Company or any of its Subsidiaries is a
          party or by which the Company or any of


                                       9



          its Subsidiaries or any of its properties is bound or affected, or
          violate or conflict with any judgment, ruling, decree, order, statute,
          rule or regulation of any court or governmental agency or body
          applicable to the business or properties of the Company or any of its
          Subsidiaries.

     (o)  The Company and each of its Subsidiaries has good and valid title to
          all properties and assets described in the Prospectus as owned by it,
          free and clear of all liens, charges, encumbrances or restrictions,
          except such as are described in the Prospectus or would not have a
          Material Adverse Effect. The Company and each of its Subsidiaries have
          valid, subsisting and enforceable leases for the properties described
          in the Prospectus as leased by it, with such exceptions as are not
          material and do not materially interfere with the use made and
          proposed to be made of such properties by the Company and such
          Subsidiaries.

     (p)  All legal or governmental proceedings, affiliate transactions,
          contracts, licenses, agreements, leases or documents of a character
          required to be described in the Registration Statement or the
          Prospectus or to be filed as an exhibit to the Registration Statement
          have been so described or filed as required. All such contracts to
          which the Company or any Subsidiary is a party have been duly
          authorized, executed and delivered by the Company or such Subsidiary,
          constitute valid and binding agreements of the Company or such
          Subsidiary and are enforceable against the Company or such Subsidiary
          in accordance with the terms thereof, subject to the effect of
          bankruptcy, insolvency, reorganization, receivership, moratorium and
          other laws affecting the rights and remedies of creditors generally
          and general equitable principles and subject to any principles of
          public policy limiting the rights to enforce any indemnification
          provisions contained herein and therein.

     (q)  No statement, representation, warranty or covenant made by the Company
          in this Agreement or made in any certificate or document required by
          this Agreement to be delivered to you was or will be, when made,
          inaccurate, untrue or incorrect in any material respect. Any
          certificate signed by any officer of the Company and delivered to you
          or your counsel in connection with the offering of the Shares shall be
          deemed a representation and warranty by the Company to you as to the
          matters covered thereby.

     (r)  Neither the Company nor any of its Subsidiaries or any of their
          respective directors, officers, affiliates or controlling persons has
          taken, directly or indirectly, any action designed, or that might
          reasonably be expected, to cause or result, under the Exchange Act or
          otherwise, in, or which has constituted, stabilization or manipulation
          of the price of any security of the Company to facilitate the sale or
          resale of the Shares.

     (s)  No holder of securities of the Company has rights to the registration
          of any securities of the Company because of the filing of the
          Registration Statement or the consummation of the transactions
          contemplated by this Agreement.


                                       10



     (t)  The Shares have been approved for listing on the New York Stock
          Exchange, subject only to official notice of issuance.

     (u)  Except as disclosed in the Registration Statement and the Prospectus,
          the Company and its Subsidiaries are in substantial compliance with
          all federal, state and local employment and labor laws, including, but
          not limited to, laws relating to non-discrimination in hiring,
          promotion and pay of employees; no labor dispute with the employees of
          the Company or any Subsidiary exists or, to the knowledge of the
          Company, is imminent or threatened; and the Company is not aware of
          any existing, imminent or threatened labor disturbance by the
          employees of any of its principal suppliers, manufacturers or
          contractors that could result in a Material Adverse Effect.

     (v)  The Company and its Subsidiaries own, or are licensed or otherwise
          have the full exclusive right to use, all material trademarks, service
          marks and trade names that are used in or necessary for the conduct of
          their respective businesses as described in the Prospectus, except for
          failures of ownership or use that would not cause a Material Adverse
          Effect. To the knowledge of the Company, no claims have been asserted
          by any person to the use of any such trademarks or trade names or
          challenging or questioning the validity or effectiveness of any such
          trademark or trade name. The use, in connection with the business and
          operations of the Company and its Subsidiaries of such trademarks and
          trade names does not, to the Company's knowledge, infringe on the
          rights of any person.

     (w)  Neither the Company nor any of its Subsidiaries nor, to the Company's
          knowledge, any employee or agent of the Company or any Subsidiary has
          made any payment of funds of the Company or any Subsidiary or received
          or retained any funds in violation of any law, rule or regulation or
          of a character required to be disclosed in the Prospectus.

     (x)  All United States federal income tax returns of the Company and its
          Subsidiaries required by law to be filed have been filed or extensions
          have been granted, and all other franchise and income tax returns of
          the Company and its Subsidiaries required to be filed pursuant to
          applicable foreign, state or local law have been filed, and all taxes
          shown by such returns or otherwise assessed, which are due and
          payable, have been paid, except tax assessments, if any, as are being
          contested in good faith and as to which adequate reserves have been
          provided and taxes that are currently payable without penalty or
          interest. The charges, accruals and reserves on the books of the
          Company and its Subsidiaries in respect of any income and corporate
          franchise tax liability for any years not finally determined are
          adequate to meet any assessments or reassessments for additional
          income or corporate franchise tax for any years not finally
          determined.

     (y)  The Company and its Subsidiaries (i) are in compliance with any and
          all applicable foreign, federal, state and local laws and regulations
          relating to the protection of human health and safety, the environment
          or imposing liability or standards of conduct concerning any Hazardous
          Material (as hereinafter defined)

                                       11



          ("Environmental Laws"), (ii) have received all permits, licenses or
          other approvals required of them under applicable Environmental Laws
          to conduct their respective businesses and (iii) are in compliance
          with all terms and conditions of any such permit, license or approval,
          except as set forth in the Registration Statement and the Prospectus
          and except where such noncompliance with Environmental Laws, failure
          to receive required permits, licenses or other approvals or failure to
          comply with the terms and conditions of such permits, licenses or
          approvals would not, individually or in the aggregate result in a
          Material Adverse Effect. The term "Hazardous Material" means (A) any
          "hazardous substance" as defined by the Comprehensive Environmental
          Response, Compensation and Liability Act of 1980, as amended, (B) any
          "hazardous waste" as defined by the Resource Conservation and Recovery
          Act, as amended, (C) any petroleum or petroleum product, (D) any
          polychlorinated biphenyl and (E) any pollutant or contaminant or
          hazardous, dangerous, or toxic chemical, material, waste or substance
          regulated under or within the meaning of any other Environmental Law.

     (z)  In the ordinary course of its business, the Company conducts a
          periodic review of the effect of Environmental Laws on the business,
          operations and properties of the Company and its Subsidiaries, in the
          course of which it identifies and evaluates associated costs and
          liabilities (including, without limitation, any capital or operating
          expenditures required for clean-up, closure of properties or
          compliance with Environmental Laws or any permit, license or approval,
          any related constraints on operating activities and any potential
          liabilities to third parties). Except as set forth in the Registration
          Statement and the Prospectus there are no costs and liabilities
          associated with or arising in connection with Environmental Laws as
          currently in effect (including, without limitation, costs of
          compliance therewith) which would, singly or in the aggregate have a
          Material Adverse Effect.

     (aa) Except as disclosed in the Registration Statement and the Prospectus,
          neither the Company nor any of its Subsidiaries has received any
          written communication, whether from a governmental authority,
          citizens' group, employee or otherwise, asserting that the Company or
          any of its Subsidiaries or any other person or entity for whom any of
          them is or may be liable is not in compliance with any Environmental
          Laws or permit or authorization required under applicable
          Environmental Laws where such failure to comply would have a Material
          Adverse Effect, and, to the knowledge of the Company, there are no
          circumstances that may prevent or interfere with such full compliance
          in the future, except where failure so to comply would not have a
          Material Adverse Effect.

     (bb) The Company has obtained for the benefit of the Underwriter the
          agreement (a "Lock-Up Agreement"), of each of the Company's directors
          and executive officers. The Company will not release or purport to
          release any person from any Lock-Up Agreement without the prior
          written consent of the Underwriter.

                                       12



     (cc) The Company and each of its Subsidiaries maintains insurance covering
          its properties, operations, personnel and businesses as the Company
          deems adequate. Such insurance insures against such losses and risks
          to an extent which is adequate in accordance with customary industry
          practice to protect the Company and its subsidiaries and their
          businesses. All such insurance is outstanding and fully in force on
          the date hereof and will be outstanding and fully in force on the
          Closing Date and the Option Closing Date, as applicable. Except as
          disclosed in the Registration Statement and the Prospectus, neither
          the Company nor any of its Subsidiaries has sustained since the date
          of the last financial statements included in the Prospectus any
          material loss or interference with their respective business from
          fire, explosion, flood or other calamity, whether or not covered by
          insurance, or from any labor dispute or court or governmental action,
          order or decree.

     (dd) With respect to each employee benefit plan, program and arrangement
          (including, without limitation, any "employee benefit plan" as defined
          in Section 3(3) of the Employee Retirement Income Security Act of
          1974, as amended ("ERISA")) maintained or contributed to by the
          Company, or with respect to which the Company could incur any
          liability under ERISA (collectively, the "Benefit Plans"), no event
          has occurred and, to the knowledge of the Company, there exists no
          condition or set of circumstances, in connection with which the
          Company could be subject to any liability under the terms of such
          Benefit Plan, applicable law (including, without limitation, ERISA and
          the Internal Revenue Code of 1986, as amended) or any applicable
          agreement, in any such case, that could have a Material Adverse
          Effect.

          developments," "Our company -- Our business strategy" and "Westar's
          ownership of our stock; transactions with Westar" (i) are within the
          coverage of Rule 175(b) under the Act to the extent such statements
          and data constitute forward-looking statements as defined in Rule
          175(c) and (ii) were made by the Company with a reasonable basis and
          reflect the Company's good faith estimate of the matters described
          therein.

          involving the Company or any of its Subsidiaries or any other person
          required to be described in the Registration Statement or the
          Prospectus that have not been described as required.

     (gg) There are no outstanding loans (except for immaterial loans related to
          appliance purchases pursuant to a discontinued program under which no
          new loans have been made since the enactment of the Sarbanes-Oxley
          Act), advances (except normal advances for business expenses in the
          ordinary course of business) or guarantees of indebtedness by the
          Company to or for the benefit of any of the officers or directors of
          the Company or any of the members of any of them.

                                       13



     (hh) Any statistical or market-related data included in the Prospectus are
          based on or derived from sources that the Company believes to be

          consent to the use of such data from such sources to the extent
          required.

     (ii) The Company has not offered, or caused the Underwriter to offer,
          Shares to any person with the specific intent to influence unlawfully

          from the Company any brokerage or finder's fee or other fee or
          commission as a result of the transactions contemplated by this
          Agreement.

     (kk) The Company is in substantial compliance with the applicable
          provisions of the Sarbanes-Oxley Act that are effective and is

          shares of Common Stock in compliance with procedures set forth in the

          Preferences and Relative, Participating, Optional or Other Rights and

          Parent and the Selling Stockholder, and the consummation by each of
          Parent and the Selling Stockholder of the transactions herein and
          therein contemplated will not (i) conflict with or result in a breach
          or violation of any of the terms or provisions of, or constitute a
          default under, or result in the creation or imposition of any lien,

          trust, loan agreement or other agreement or instrument to which either
          Parent or the Selling Stockholder is a party or by which either Parent

          court or arbitrator or governmental or regulatory agency.

     (d)  After giving effect to the conversion of shares of the Series D
          Preferred Stock into shares of Common Stock contemplated by the
          Transaction Agreement, each of Parent and the Selling Stockholder has
          good and valid title to the Shares to be sold by it hereunder at the
          Closing Date or the Option Closing Date, as the case may be, free and
          clear of all liens, encumbrances, equities or adverse claims; Parent
          and the Selling Stockholder will have, immediately prior to the
          Closing Date or the Option Closing Date, as the case may be, good and
          valid title to the Shares to be sold by it at the Closing Date or the
          Option Closing Date, as the case may be, free and clear of all liens,

          liens, encumbrances, equities or adverse claims (other than any
          adverse claims of which the Underwriter has notice), will pass to the
          Underwriter.

     (e)  Neither Parent nor the Selling Stockholder has taken, directly or
          indirectly, any action designed to or that could reasonably be
          expected to cause or result in any stabilization or manipulation of
          the price of the Common Stock.

     (f)  As of the applicable effective date of the Registration Statement and
          any amendment thereto, the Registration Statement complied and will
          comply in all material respects with the Securities Act, and did not
          and will not contain any untrue statement of a material fact or omit
          to state a material fact required to be stated therein or necessary in
          order to make the statements therein not misleading; and as of the
          applicable filing date of the Prospectus and any amendment or
          supplement thereto and as of the Closing Date and as of the Option
          Closing Date,

                                       15



          as the case may be, the Prospectus will not contain any untrue
          statement of a material fact or omit to state a material fact required
          to be stated therein or necessary in order to make the statements
          therein, in the light of the circumstances under which they were made,

          warranty shall only apply to any statements or omissions made in
          reliance upon and in conformity with information relating to Parent
          and the Selling Stockholder furnished in writing to the Company by
          Parent and the Selling Stockholder expressly for use therein.

     (g)  Within the preceding 180 days, neither Parent nor the Selling
          Stockholder, nor any other person acting on behalf of Parent or the

          which the Selling Stockholder makes no representation), has offered or
          sold to any person any Common Stock other than the Shares offered or
          sold to the Underwriter hereunder.

     (h)  Neither Parent nor the Selling Stockholder have entered and neither of
          them will enter into any contractual arrangement with respect to the
          distribution of the Shares except for this Agreement, the Custody
          Agreement, the Transaction Agreement, the Registration Rights
          Agreement, dated as of January 9, 2003, by and among the Company,

          declaration with, any court or governmental agency or body is required
          in connection with the transfer, sale or delivery of the Shares by
          Parent or the Selling Stockholder, in connection with the execution,
          delivery and performance of this Agreement by Parent or the Selling
          Stockholder or in connection with the taking by Parent or the Selling
          Stockholder of any action contemplated hereby, except such (i) as have
          been obtained under the Act or the Rules and Regulations, (ii) as may
          be required under state securities or Blue Sky laws or the by-laws and
          rules of the NASD in connection with the purchase and distribution by
          the Underwriters of the Shares and (iii) as have been obtained from
          the Kansas Corporation Commission.

     (j)  Each of Parent and the Selling Stockholder represents and warrants
          that certificates in negotiable form representing (with respect to
          those Shares that will be sold upon conversion of the Series D
          Preferred Stock, upon such conversion), all of the Shares to be sold
          by Parent or the Selling Stockholder hereunder have been placed in
          custody under a Custody Agreement relating to such Shares, in the form
          heretofore furnished to you, duly executed and delivered by Parent or
          the Selling Stockholder to UMB Bank, n.a., as custodian (the
          "Custodian").

     (k)  Each of Parent and the Selling Stockholder specifically agrees that
          the Shares represented by the certificates held in custody for Parent
          or the Selling Stockholder under the Custody Agreement, are subject to
          the interests of the

                                       16



          Underwriter, and that the arrangements made by Parent and the Selling
          Stockholder for such custody is to that extent irrevocable.

5.   Agreements of the Company. The Company agrees with the Underwriter as
     follows:

     (a)  The Company will not, during such period as the Prospectus is required
          by law to be delivered in connection with sales of the Shares by an
          Underwriter or a dealer (the "Prospectus Delivery Period"), file any
          amendment or supplement to the Registration Statement or the
          Prospectus, unless a copy thereof shall first have been submitted to
          the Underwriter within a reasonable period of time prior to the filing
          thereof and the Underwriter shall not have objected thereto in good
          faith.

     (b)  The Company will notify the Underwriter promptly, and will confirm
          such advice in writing, (i) when any post-effective amendment to the
          Registration Statement becomes effective, (ii) of any request by the
          Commission for amendments or supplements to the Registration Statement
          or the Prospectus or for additional information, (iii) of the issuance
          by the Commission of any stop order suspending the effectiveness of
          the Registration Statement or the initiation of any proceedings for
          that purpose or the threat thereof, (iv) of the happening of any event
          during the period mentioned in the second sentence of subsection (e)
          that in the judgment of the Company makes any statement made in the
          Registration Statement or the Prospectus untrue or that requires the
          making of any changes in the Registration Statement or the Prospectus
          in order to make the statements therein, in light of the circumstances
          in which they are made, not misleading and (v) of receipt by the
          Company or any representative or attorney of the Company of any other
          communication from the Commission relating to the Company, the
          Registration Statement, any preliminary prospectus or the Prospectus.
          If at any time the Commission shall issue any order suspending the
          effectiveness of the Registration Statement, the Company will make
          every reasonable effort to obtain the withdrawal of such order at the
          earliest possible moment. The Company will use its best efforts to
          comply with the provisions of and make all requisite filings with the
          Commission pursuant to Rule 430A and to notify the Underwriter
          promptly of all such filings.

     (c)  The Company has furnished, or will furnish, to the Underwriter,
          without charge, two conformed copies of the Registration Statement and
          of any post-effective amendment thereto, including financial
          statements and schedules, and all exhibits thereto (including any
          document filed under the Exchange Act and deemed to be incorporated by
          reference into the Prospectus).

     (d)  The Company will comply with all the provisions of any undertakings
          contained in the Registration Statement.

     (e)  On the Effective Date, and thereafter from time to time, the Company
          will deliver to the Underwriter, without charge, as many copies of the
          Prospectus or any amendment or supplement thereto as the Underwriter
          may reasonably request.

                                       17



          The Company consents to the use of the Prospectus or any amendment or
          supplement thereto by the Underwriter and by all dealers to whom the
          Shares may be sold, both in connection with the offering or sale of
          the Shares and during the Prospectus Delivery Period. If, during the
          Prospectus Delivery Period any event shall occur that in the judgment
          of the Company or counsel to the Underwriter should be set forth in
          the Prospectus in order to make any statement therein, in the light of
          the circumstances under which it was made, not misleading, or if it is
          necessary to supplement or amend the Prospectus to comply with law,
          the Company will forthwith prepare and duly file with the Commission
          an appropriate supplement or amendment thereto, and will deliver to
          the Underwriter, without charge, such number of copies thereof as the
          Underwriter may reasonably request. The Company shall not file any
          document under the Exchange Act before the termination of the offering
          of the Shares by the Underwriter if such document would be deemed to
          be incorporated by reference into the Prospectus and if such document
          is not approved by the Underwriter after reasonable notice thereof.

     (f)  Prior to any public offering of the Shares by the Underwriter, the
          Company will cooperate with the Underwriter and counsel to the
          Underwriter in connection with the registration or qualification of
          the Shares for offer and sale under the securities or Blue Sky laws of
          such jurisdictions as the Underwriter may request; provided, that in
          no event shall the Company be obligated to qualify to do business in
          any jurisdiction where it is not now so qualified or to take any
          action which would subject it to general service of process in any
          jurisdiction where it is not now so subject.

     (g)  During the period of two years commencing on the date of the Price
          Determination Agreement, the Company will furnish to the Underwriter
          copies of such financial statements and other periodic and special
          reports as the Company may from time to time distribute generally to
          the holders of any class of its capital stock, and will furnish to the
          Underwriter a copy of each annual or other report it shall be required
          to file with the Commission.

     (h)  The Company will make generally available to its security holders and
          the Underwriter as soon as practicable an earning statement that
          satisfies the provisions of Section 11(a) of the Securities Act and
          Rule 158 of the Commission promulgated thereunder covering a period of
          at least twelve months beginning with the first fiscal quarter of the
          Company occurring after the "effective date" (as defined in Rule 158)
          of the Registration Statement.

     (i)  The Company will not at any time, directly or indirectly, take any
          action intended, or that might reasonably be expected, to cause or
          result in, or which will constitute, stabilization of the price of the
          shares of Common Stock to facilitate the sale or resale of any of the
          Shares.

     (j)  The Company shall cause to be prepared and delivered, at its expense,
          within one business day from the effective date of this Agreement, to
          the

                                       18



          Underwriter an "electronic Prospectus" to be used by the Underwriter
          in connection with the offering and sale of the Shares. As used
          herein, the term "electronic Prospectus" means a form of Prospectus,
          and any amendment or supplement thereto, that meets each of the
          following conditions: (i) it shall be encoded in an electronic format,
          satisfactory to the Underwriter, that may be transmitted
          electronically by the Underwriter to offerees and purchasers of the
          Shares for at least the Prospectus Delivery Period; (ii) it shall
          disclose the same information as the paper Prospectus and Prospectus
          filed pursuant to EDGAR, except to the extent that graphic and image
          material cannot be disseminated electronically, in which case such
          graphic and image material shall be replaced in the electronic
          Prospectus with a fair and accurate narrative description or tabular
          representation of such material, as appropriate; and (iii) it shall be
          in or convertible into a paper format or an electronic format,
          satisfactory to the Underwriter, that will allow investors to store
          and have continuously ready access to the Prospectus at any future
          time, without charge to investors (other than any fee charged for
          subscription to the Internet as a whole and for on-line time). The
          Company hereby confirms that it has included or will include in the
          Prospectus filed pursuant to EDGAR or otherwise with the Commission
          and in the Registration Statement at the time it was declared
          effective an undertaking that, upon receipt of a request by an
          investor or his or her representative within the Prospectus Delivery
          Period, the Company shall transmit or cause to be transmitted
          promptly, without charge, a paper copy of the Prospectus.

     (k)  During the 90-day period beginning on the date of this Agreement, the
          Company will not without the prior written consent of the Underwriter
          (which consent may be withheld at the sole discretion of the
          Underwriter), directly or indirectly, sell, offer, contract or grant
          any option to sell, pledge, transfer or establish an open "put
          equivalent position" within the meaning of Rule 16a-1(h) under the
          Exchange Act, or otherwise dispose of or transfer, or file with the
          Commission a registration statement under the Act relating to, any
          shares of Common Stock or securities convertible into or exchangeable
          for any shares of Common Stock, or publicly disclose the intention to
          make any such offer, sale, pledge, transfer, disposition or filing,
          except for (i) issuances pursuant to employee or director compensation
          plans existing on the date of this Agreement, including issuances
          pursuant to the exercise of stock options outstanding on the date of
          this Agreement, (ii) grants of employee or director stock options
          pursuant to the terms of a plan in effect on the date of this
          Agreement, (iii) issuances pursuant to the exercise of such employee
          or director stock options, (iv) the filing of registration statements
          on Form S-8 and amendments thereto in connection with such employee or

          employee thrift plans or direct stock purchase or dividend
          reinvestment plans in place on the date of this Agreement and (vi) the

          the acquiror of such shares or options agrees to the foregoing
          restrictions.

          the satisfaction of the staff of the Commission or such authorities
          and (iv) after the date hereof no amendment or supplement to the

          Section 15 of the Act or Section 20 of the Exchange Act from and
          against any and all losses, claims, liabilities, expenses and damages

          any of the indemnified parties and any indemnifying parties or between
          any indemnified party and any third party, or otherwise, or any claim
          asserted), as and when incurred, to which the Underwriter, or any such
          person, may become

                                       26



          subject under the Act, the Exchange Act or other federal or state
          statutory law or regulation, at common law or otherwise, insofar as
          such losses, claims, liabilities, expenses or damages arise out of or
          are based on (i) any untrue statement or alleged untrue statement of a
          material fact contained in any preliminary prospectus, the
          Registration Statement or the Prospectus or any amendment or
          supplement to the Registration Statement or the Prospectus or in any
          documents filed under the Exchange Act and deemed to be incorporated
          by reference into the Prospectus, or in any application or other
          document executed by or on behalf of the Company or based on written
          information furnished by or on behalf of the Company filed in any
          jurisdiction in order to qualify the Shares under the securities laws
          thereof or filed with the Commission, (ii) the omission or alleged
          omission to state in such document a material fact required to be
          stated in it or necessary to make the statements in it not misleading
          or (iii) any act or failure to act or any alleged act or failure to
          act by the Underwriter in connection with, or relating in any manner

          expense or damage arising out of or based upon matters covered by
          clause (i) or (ii) above (provided that the Company shall not be
          liable under this clause (iii) to the extent it is finally judicially
          determined by a court of competent jurisdiction that such loss, claim,
          liability, expense or damage resulted directly from any such acts or
          failures to act undertaken or omitted to be taken by the Underwriter
          through its gross negligence or willful misconduct); provided that the
          Company will not be liable to the extent that such loss, claim,
          liability, expense or damage arises from the sale of the Shares in the
          public offering to any person by the Underwriter and is based on an
          untrue statement or omission or alleged untrue statement or omission
          made in reliance on and in conformity with information relating to the
          Underwriter furnished in writing to the Company by the Underwriter
          expressly for inclusion in the Registration Statement, any preliminary
          prospectus or the Prospectus. This indemnity agreement will be in
          addition to any liability that the Company might otherwise have.

     (b)  Parent and the Selling Stockholder, jointly and severally, agree to
          indemnify and hold harmless the Underwriter, its affiliates, directors
          and officers and each person, if any, who controls the Underwriter
          within the meaning of Section 15 of the Securities Act or Section 20
          of the Exchange Act, from and against any and all losses, claims,
          damages and liabilities (including, without limitation, the legal fees
          and other expenses incurred in connection with any suit, action or
          proceeding or any claim asserted, as such fees and expenses are
          incurred), joint or several, that arise out of, or are based upon, any
          untrue statement or alleged untrue statement of a material fact
          contained in the Registration Statement, any preliminary prospectus or
          the Prospectus, or caused by any omission or alleged omission to state
          therein a material fact required to be stated therein or necessary to
          make the statements therein, in the light of the circumstances under
          which they were made, not misleading, but only insofar as losses,
          claims, liabilities, expenses or damages arise out of or are based on
          any untrue statement or omission or alleged untrue statement or
          omission made in reliance upon and in conformity with written
          information relating to Parent or the


                                       27



          Selling Stockholder furnished in writing to the Company or the
          Underwriter by Parent or the Selling Stockholder for use in the
          Registration Statement or Prospectus and except insofar as such
          losses, claims, damages or liabilities arise out of, or are based
          upon, any untrue statement or omission or alleged untrue statement or
          omission made in reliance upon and in conformity with information
          relating to the Underwriter furnished to the Company in writing by the
          Underwriter expressly for use therein, it being understood and agreed
          that the only such information furnished by the Underwriter consists
          of the information described as such in subsection (c) below.

     (c)  The Underwriter agrees to indemnify and hold harmless the Company,
          each person, if any, who controls the Company within the meaning of
          Section 15 of the Act or Section 20 of the Exchange Act, each director
          of the Company and each officer of the Company who signs the
          Registration Statement and Parent and the Selling Stockholder to the
          same extent as the foregoing indemnity from the Company to the
          Underwriter, but only insofar as losses, claims, liabilities, expenses
          or damages arise out of or are based on any untrue statement or
          omission or alleged untrue statement or omission made in reliance on
          and in conformity with written information relating to the Underwriter
          furnished in writing to the Company by the Underwriter expressly for
          use in the Registration Statement or the Prospectus, it being
          understood and agreed upon that the only such information furnished by
          the Underwriter consists of the following information in the
          Prospectus furnished on behalf of the Underwriter: the concession and
          reallowance figures appearing in the fifth paragraph under the caption
          "Underwriting" and the information contained in the thirteenth and
          fourteenth paragraphs under the caption "Underwriting." This indemnity
          agreement will be in addition to any liability that the Underwriter
          may otherwise have; provided, however, that in no case will the
          Underwriter be liable or responsible for any amount in excess of the
          underwriting discounts and commissions received by the Underwriter.

     (d)  Any party that proposes to assert the right to be indemnified under
          this Section 10 will, promptly after receipt of notice of commencement
          of any action against such party in respect of which a claim is to be
          made against an indemnifying party or parties under this Section 10,
          notify each such indemnifying party of the commencement of such
          action, enclosing a copy of all papers served, but the omission so to
          notify such indemnifying party will not relieve it from any liability
          that it may have to any indemnified party under the foregoing
          provisions of this Section 10 unless, and only to the extent that,
          such omission results in the forfeiture of substantive rights or
          defenses by the indemnifying party. If any such action is brought
          against any indemnified party and it notifies the indemnifying party
          of its commencement, the indemnifying party will be entitled to
          participate in and, to the extent that it elects by delivering written
          notice to the indemnified party promptly after receiving notice of the
          commencement of the action from the indemnified party to assume the
          defense of the action, with counsel satisfactory to the indemnified
          party, and after notice from the indemnifying party to the indemnified
          party of its election to assume the


                                       28



          defense, the indemnifying party will not be liable to the indemnified
          party for any legal or other expenses except as provided below and
          except for the reasonable costs of investigation subsequently incurred
          by the indemnified party in connection with the defense. The
          indemnified party will have the right to employ its own counsel in any
          such action, but the fees, expenses and other charges of such counsel
          will be at the expense of such indemnified party unless (i) the
          employment of counsel by the indemnified party has been authorized in
          writing by the indemnifying party, (ii) the indemnified party has
          reasonably concluded (based on advice of counsel) that there may be
          legal defenses available to it or other indemnified parties that are
          different from or in addition to those available to the indemnifying
          party, (iii) a conflict or potential conflict exists (based on advice
          of counsel to the indemnified party) between the indemnified party and
          the indemnifying party (in which case the indemnifying party will not
          have the right to direct the defense of such action on behalf of the
          indemnified party) or (iv) the indemnifying party has not in fact
          employed counsel to assume the defense of such action within a
          reasonable time after receiving notice of the commencement of the
          action, in each of which cases the reasonable fees, disbursements and
          other charges of counsel will be at the expense of the indemnifying
          party or parties. It is understood that the indemnifying party shall
          not, in connection with any proceeding or related proceedings in the
          same jurisdiction, be liable for the fees, disbursements and other
          charges of more than one separate firm admitted to practice in such
          jurisdiction at any one time for all such indemnified party or
          parties. All such fees, disbursements and other charges will be
          reimbursed by the indemnifying party promptly as they are incurred. An
          indemnifying party will not be liable for any settlement of any action
          or claim effected without its written consent (which consent will not
          be unreasonably withheld). No indemnifying party shall, without the
          prior written consent of each indemnified party, settle or compromise
          or consent to the entry of any judgment in any pending or threatened
          claim, action or proceeding relating to the matters contemplated by
          this Section 10 (whether or not any indemnified party is a party
          thereto), unless such settlement, compromise or consent includes an
          unconditional release of each indemnified party from all liability
          arising or that may arise out of such claim, action or proceeding.
          Notwithstanding any other provision of this subsection (d), if at any
          time an indemnified party shall have requested an indemnifying party
          to reimburse the indemnified party for fees and expenses of counsel,
          such indemnifying party agrees that it shall be liable for any
          settlement effected without its written consent if (1) such settlement
          is entered into more than 45 days after receipt by such indemnifying
          party of the aforesaid request, (2) such indemnifying party shall have
          received notice of the terms of such settlement at least 30 days prior
          to such settlement being entered into and (3) such indemnifying party
          shall not have reimbursed such indemnified party in accordance with
          such request prior to the date of such settlement.

     (e)  In order to provide for just and equitable contribution in
          circumstances in which the indemnification provided for in subsections
          (a), (b) and (c) is applicable in accordance with its terms but for
          any reason is held to be unavailable to an indemnified party
          thereunder or insufficient in respect of any losses, claims,

                                       29



          liabilities, expenses and damages referred to therein, then each
          indemnifying party under such paragraph, in lieu of indemnifying such
          indemnified party thereunder, shall contribute to the total losses,
          claims, liabilities, expenses and damages (including any
          investigative, legal and other expenses reasonably incurred in
          connection with, and any amount paid in settlement of, any action,
          suit or proceeding or any claim asserted, but after deducting any
          contribution received by the Company, Parent or the Selling
          Stockholder from persons other than the Underwriter, such as persons
          who control the Company or Parent or the Selling Stockholder within
          the meaning of the Act, officers of the Company who signed the
          Registration Statement and directors of the Company, who also may be
          liable for contribution) to which the Company (in the case of losses,
          claims, liabilities, expenses and damages arising from the Company's
          obligations under subsection (a)) or Parent or the Selling Stockholder
          (in the case of losses, claims, liabilities, expenses and damages
          arising from the obligations of Parent and the Selling Stockholder
          under subsection (b)) on the one hand and the Underwriter on the other
          may be subject in such proportion as shall be appropriate to reflect
          the relative benefits received by the Company on the one hand and the
          Underwriter on the other (in the case of losses, claims, liabilities,
          expenses and damages arising under subsections (a) or (c)) or Parent
          or the Selling Stockholder on the one hand and the Underwriter on the
          other (in the case of losses, claims, liabilities, expenses and
          damages arising under subsections (b) or (c)). If, but only if, the
          allocation provided by the foregoing sentence is not permitted by
          applicable law, the allocation of contribution shall be made in such
          proportion as is appropriate to reflect not only the relative benefits
          referred to in the foregoing sentence but also the relative fault of
          the Company or Parent or the Selling Stockholder on the one hand and
          the Underwriter on the other, with respect to the statements or
          omissions that resulted in such loss, claim, liability, expense or
          damage, or action in respect thereof, as well as any other relevant
          equitable considerations with respect to such offering. The relative
          benefits received by the Company or Parent or the Selling Stockholder
          on the one hand and the Underwriter on the other shall be deemed to be
          in the same respective proportions as the total net proceeds (before
          deducting expenses) from the sale of the Shares and the total
          underwriting discounts and commissions received by the Underwriter in
          connection therewith, in each case as set forth in the table on the
          cover of the Prospectus, bear to the aggregate offering price of the
          Shares. The relative fault of the Company (in the case of losses,
          claims, liabilities, expenses and damages arising from the Company's
          obligations under subsection (a)) or Parent or the Selling Stockholder
          (in the case of losses, claims, liabilities, expenses and damages
          arising from the obligations of Parent or the Selling Stockholder
          under subsection (b)) on the one hand and the Underwriter on the other
          shall be determined by reference to, among other things, whether the
          untrue or alleged untrue statement of a material fact or the omission
          or alleged omission to state a material fact related to information
          supplied by the Company one the one hand or the Underwriter on the
          other (in the case of losses, claims, liabilities, expenses and
          damages arising under subsections (a) or (c)) or Parent or the Selling
          Stockholder on the one hand and the Underwriter on the other (in the
          case

                                       30



          of losses, claims, liabilities, expenses and damages arising under
          subsections (b) or (c)), the relative intent of the parties and their
          relative knowledge, access to information and opportunity to correct
          or prevent such statement or omission. The Company, Parent, the
          Selling Stockholder and the Underwriter agree that it would not be
          just and equitable if contributions pursuant to this subsection (e)
          were to be determined by pro rata allocation or by any other method of
          allocation which does not take into account the equitable
          considerations referred to herein. The amount paid or payable by an
          indemnified party as a result of the loss, claim, liability, expense
          or damage, or action in respect thereof, referred to above in this
          subsection (e) shall be deemed to include, for purpose of this
          subsection (e), any legal or other expenses reasonably incurred by
          such indemnified party in connection with investigating or defending
          any such action or claim. Notwithstanding the provisions of this
          subsection (e), the Underwriter shall not be required to contribute
          any amount in excess of the underwriting discounts and commissions
          received by it and no person found guilty of fraudulent
          misrepresentation (within the meaning of Section 11(f) of the Act)
          will be entitled to contribution from any person who was not guilty of
          such fraudulent misrepresentation. For purposes of this subsection
          (e), any person who controls a party to this Agreement within the
          meaning of the Act will have the same rights to contribution as that
          party, and each officer of the Company who signed the Registration
          Statement will have the same rights to contribution as the Company,
          subject in each case to the provisions hereof. Any party entitled to
          contribution, promptly after receipt of notice of commencement of any
          action against such party in respect of which a claim for contribution
          may be made under this subsection (e), will notify any such party or
          parties from whom contribution may be sought, but the omission so to
          notify will not relieve the party or parties from whom contribution
          may be sought from any other obligation it or they may have under this
          subsection (e). Except for a settlement entered into pursuant to the
          last sentence of subsection (d) hereof, no party will be liable for
          contribution with respect to any action or claim settled without its
          written consent (which consent will not be unreasonably withheld). In
          no event shall the obligations of either Parent or the Selling
          Stockholder under the foregoing contribution exceed the net proceeds
          received by Parent or the Selling Stockholder, as the case may be,
          from the sale of the Shares sold by it hereunder (which net proceeds
          shall not include the Underwriter's discounts).

     (f)  The indemnity and contribution agreements contained in this Section 10
          and the representations and warranties of the Company, Parent and the
          Selling Stockholder contained in this Agreement shall remain operative
          and in full force and effect regardless of (i) any investigation made
          by or on behalf of the Underwriter, (ii) acceptance of the Shares and
          payment therefor or (iii) any termination of this Agreement.

11.  Termination. The obligations of the Underwriter under this Agreement may be
     terminated at any time on or prior to the Closing Date (or, with respect to
     the Option Shares, on or prior to the Option Closing Date), by notice from
     the Underwriter to the Company, Parent and the Selling Stockholder if,
     prior to delivery and payment for the

                                       31



     Shares (or the Option Shares, as the case may be), in the sole judgment of
     the Underwriter, (a) there has been, since the respective dates as of which
     information is given in the Registration Statement and the Prospectus, any
     material adverse change or any development involving a prospective change,
     which has had or is reasonably likely to have a Material Adverse Effect;
     (b) trading in any of the equity securities of the Company shall have been
     suspended by the Commission, the NASD or the New York Stock Exchange; (c)
     trading in securities generally on the New York Stock Exchange or the
     Nasdaq National Market shall have been suspended or limited or minimum or
     maximum prices shall have been generally established on such exchange or
     automated quotation system, or additional material governmental
     restrictions, not in force on the date of this Agreement, shall have been
     imposed upon trading in securities generally by the New York Stock Exchange
     or The Nasdaq Stock Market or by order of the Commission or the NASD or any
     court or other governmental authority; (d) a general banking moratorium
     shall have been declared by federal or New York or Oklahoma state
     authorities; (e) there shall have occurred any outbreak or escalation of
     national or international hostilities or any crisis or calamity, or any
     change in the United States or international financial or securities
     markets, or any substantial change or development involving a prospective
     substantial change in national or international political, financial or
     economic conditions, as in the judgment of the Underwriter is material and
     adverse and makes it impractical or inadvisable to market the Shares in the
     manner and on the terms described in the Prospectus or to enforce contracts
     for the sale of securities; (f) any downgrading, or placement on any watch
     list for possible downgrading, in the rating of the Company's debt
     securities by any "nationally recognized statistical rating organization"
     (as defined for purposes of Rule 436(g) under the Exchange Act); (g) the
     taking of any action by any governmental body or agency in respect of its
     monetary or fiscal affairs that in the judgment of the Underwriter has a
     material adverse effect on the securities markets in the United States; or
     (h) the Company shall have sustained a loss by strike, fire, flood,
     earthquake, accident or other calamity of such character as in the judgment
     of the Underwriter may interfere materially with the business and
     operations of the Company regardless of whether of not such loss shall have
     been insured. Any termination pursuant to this Section 11 shall be without
     liability on the part of (i) the Company, Parent or the Selling Stockholder
     to the Underwriter, except that Parent and the Selling Stockholder shall be
     obligated to reimburse the expenses of the Underwriter pursuant to Sections
     5, 6 and 8 hereof, (ii) the Underwriter to the Company, Parent or the
     Selling Stockholder or (iii) of any party hereto to any other party except
     that the provisions of Section 10 shall at all times be effective and shall
     survive such termination.

12.  Miscellaneous.

          11 may be made by telecopy or telephone, but if so made shall be
          subsequently confirmed in writing.

     (b)  This Agreement has been and is made solely for the benefit of the
          Underwriter, the Company, Parent and the Selling Stockholder and of
          the controlling persons, directors and officers referred to in Section
          10, and their respective successors and assigns, and no other person
          shall acquire or have any right under or by virtue of this Agreement.
          The term "successors and assigns" as used in this Agreement shall not
          include a purchaser, as such purchaser, of Shares from the
          Underwriter.

     (c)  All representations, warranties and agreements of the Company, Parent
          and the Selling Stockholder contained herein or in certificates or
          other instruments delivered pursuant hereto, shall remain operative
          and in full force and effect regardless of any investigation made by
          or on behalf of the Underwriter or any of its controlling persons and
          shall survive delivery of and payment for the Shares hereunder.

     (d)  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
          THE LAWS OF THE STATE OF NEW YORK.

     (e)  Except as set forth below, no claim may be commenced, prosecuted or
          continued in any court other than the courts of the State of New York
          located in the City and County of New York or in the United States
          District Court for the Southern District of New York, which courts
          shall have jurisdiction of such courts and personal service with
          respect thereto. Each of the Company, Parent and the Selling
          Stockholder hereby consents to personal jurisdiction, service and
          venue in any court in which any claim arising out of or in any way
          relating to this Agreement is brought by any third party against any
          indemnified party. Each of the Underwriter, the Company (on its behalf
          and, to the extent permitted by applicable law, on behalf of all
          indemnified parties and its and their stockholders and affiliates),
          Parent and the Selling Stockholder waives all right to trial by jury
          in any action, proceeding or counterclaim (whether based upon
          contract, tort or otherwise) in any way arising out of or relating to
          this Agreement. Each of the Company, Parent and the Selling
          Stockholder agrees that a final judgment in any such action,
          proceeding or counterclaim brought in any such court shall be
          conclusive and binding upon each of the Company, Parent and the
          Selling Stockholder and may be enforced in any other courts in the
          jurisdiction of which the Company, Parent or the Selling Stockholder
          is or may be subject, by suit upon such judgment.

     (f)  This Agreement may be signed in two or more counterparts with the same
          effect as if the signatures thereto and hereto were upon the same
          instrument.

                                       33



     (g)  In case any provision in this Agreement shall be invalid, illegal or
          unenforceable, the validity, legality and enforceability of the
          remaining provisions shall not in any way be affected or impaired
          thereby.

     (h)  The Company, Parent, the Selling Stockholder and the Underwriter each
          hereby irrevocably waives any right they may have to a trial by jury
          in respect of any claim based upon or arising out of this Agreement or
          the transactions contemplated hereby.

     (i)  This Agreement may not be amended or otherwise modified or any
          provision hereof waived except by an instrument in writing signed by
          the Underwriter, Parent, the Selling Stockholder and the Company.

     and paid for in accordance with the provisions of the Agreement, will be,
     duly authorized, validly issued, fully paid and nonassessable and will not

     incorporation, by-laws or other organizational document of the Company or
     any significant subsidiary or the laws of the State of Oklahoma, (b)
     co-sale right, (c) right of first refusal or (d) other similar right.
     Except as described in the Registration Statement or the Prospectus or in
     the documents incorporated therein by reference or in any thrift plan,
     dividend reinvestment or direct stock purchase plan or any employee or
     director compensation arrangements pursuant to a plan in effect on the date
     of this opinion, to such counsel's knowledge, there is no commitment or
     arrangement to issue, and there are no outstanding options, warrants or
     other rights calling for the issuance of, any share of capital stock of the
     Company or any Subsidiary to any person or any security or other instrument
     that by its terms is convertible into, exercisable for or exchangeable for
     capital stock of the Company.

3.   No consent, approval, authorization or order of, or any filing or
     declaration with, any court or governmental agency or body is required to
     be obtained by the Company in connection with (a) the

                                      B-1



     issuance of shares of Common Stock upon conversion of shares of Series D
     Preferred Stock by the Selling Stockholder, (b) the transfer, sale or
     delivery of the Shares by Parent or the Selling Stockholder, (c) the
     execution, delivery and performance of the Agreement by the Company or (d)
     the taking by the Company of any action contemplated thereby except such as
     (1) have been obtained under the Act and the Rules and Regulations and (2)
     may be required under state securities or "Blue Sky" laws or by the by-laws
     and rules of the NASD in connection with the purchase and distribution by
     the Underwriter of the Shares to be sold by the Company.

4.   The authorized, issued and outstanding capital stock of the Company is as
     set forth in the Registration Statement and the Prospectus. The form of
     certificate used to evidence the Common Stock and filed as an Exhibit to
     the Registration Statement is in due and proper form and complies with all
     applicable statutory requirements.

5.   All issued and outstanding shares of capital stock or other equity
     interests of each significant subsidiary (as defined in Rule 1-02(w) of
     Regulation S-X of the Rules and Regulations) of the Company have been duly
     authorized and validly issued and, to such counsel's knowledge, have not
     been issued in violation of or subject to (a) any preemptive right arising
     under the certificate of incorporation, by-laws or other organizational
     document of the Company or such significant subsidiary or the laws of the
     State of Oklahoma, (b) co-sale right, (c) right of first refusal or (d)
     other similar right. To such counsel's knowledge, all of the shares of

     Company free and clear of any security interests, liens, encumbrances and
     claims whatsoever.

6.   The Registration Statement and the Prospectus (including any documents
     incorporated by reference into the Prospectus, at the time they were filed)
     comply or complied in all material respects as to form with the
     requirements of the Act, the Rules and Regulations, the Exchange Act and
     the Exchange Act Rules and Regulations (except that such counsel need not
     express an opinion as to financial statements, schedules and other
     financial data contained in the Registration Statement or the Prospectus or
     incorporated by reference therein).

     captions "Transaction Agreement with Westar" and

                                      B-2



     "Description of Capital Stock," insofar as such statements purport to
     summarize the legal matters or documents referred to therein, present fair
     summaries of such legal matters and documents.

8.   To such counsel's knowledge, (a) any instrument, document, lease, license,
     contract or other agreement (collectively, "Documents") required to be
     described or referred to in the Registration Statement or the Prospectus
     has been properly described or referred to therein, and (b) any Document
     required to be filed as an exhibit to the Registration Statement has been
     filed as an exhibit thereto or has been incorporated as an exhibit by
     reference in the Registration Statement or Prospectus; and, to such
     counsel's knowledge, no default exists in the due performance or observance
     of any obligation, agreement, covenant or condition contained in any
     Document filed or required to be filed as an exhibit to the Registration
     Statement.

9.   To such counsel's knowledge, no person or entity has the right to require
     the registration under the Act of shares of Common Stock or other
     securities of the Company by reason of the filing or effectiveness of the
     Registration Statement.

10.  To such counsel's knowledge, the Company is not in violation of, or in
     default with respect to, any law, rule, regulation, order, judgment or
     decree, except as may be described in the Registration Statement and the
     Prospectus (including the documents incorporated by reference therein) or
     such as in the aggregate do not now have and would not reasonably be
     expected to have a Material Adverse Effect.

11.  All descriptions in the Prospectus of statutes, regulations or legal or
     governmental proceedings are accurate and fairly present the information
     required to be shown in all material respects.

12.  The Company has full corporate power and authority to enter into the
     Agreement and the Transaction Agreement, and the Agreement and the
     Transaction Agreement have been duly authorized, executed and delivered by
     the Company, are legal, valid and binding obligations of the Company,
     enforceable against the Company in accordance with their respective terms,
     subject to the effect of bankruptcy, insolvency, reorganization,
     receivership, moratorium and other laws affecting the rights and remedies
     of creditors generally and general equitable principles and subject to any
     principles of public policy limiting the rights to enforce any
     indemnification provisions contained therein.

                                      B-3



13.  The execution and delivery by the Company of, and the performance by the
     Company of its agreements in, the Agreement and the Transaction Agreement
     do not and will not (a) violate the certificate of incorporation or by-laws
     of the Company, (b) breach or result in a default under, cause the time for
     performance of any obligation to be accelerated under, or result in the
     creation or imposition of any lien, charge or encumbrance upon any of the
     assets of the Company or any of its Subsidiaries pursuant to the terms of,
     any indenture, mortgage, deed of trust, loan agreement, bond, debenture,
     note agreement, capital lease or other evidence of indebtedness of which
     such counsel has knowledge, (c) breach or result in a default under, cause
     the time for performance of any obligation to be accelerated under, or
     result in the creation or imposition of any lien, charge or encumbrance
     upon any of the assets of the Company or any of its assets pursuant to the
     terms of, any (i) voting trust arrangement or any contract or other
     agreement to which the Company is a party that restricts the ability of the
     Company to issue securities of which such counsel has knowledge or (ii)
     Document filed as an exhibit to, or incorporated as an exhibit by reference

     applicable provisions of any statute or regulation in the State of Oklahoma
     or of the United States; except with respect to items (b), (c) and (d)
     above, such conflicts, agreements, breaches, violations or defaults as
     would not have a Material Adverse Effect.

14.  The Company is not an "investment company" or an "affiliated person" of, or
     "promoter" or "principal underwriter" for, an "investment company," as such
     terms are defined in the Investment Company Act of 1940, as amended.

15.  The Shares have been duly authorized for listing on the New York Stock
     Exchange upon official notice of issuance.

     Such counsel hereby confirms to the Underwriter that such counsel has been
orally advised by the Commission that the Registration Statement has become
effective under the Act and that, to such counsel's knowledge, no order
suspending the effectiveness of the Registration Statement has been issued and
no proceeding for that purpose has been instituted or is threatened, pending or
contemplated.

     Such counsel hereby further confirms to the Underwriter that, to such
counsel's knowledge, there are no actions, suits, proceedings or investigations
pending or overtly threatened in writing against the Company or any of its
Subsidiaries, or any of their respective officers or directors in their
capacities as such, before or by any court, governmental agency or

                                      B-4



arbitrator that (i) seek to challenge the legality or enforceability of the
Agreement or the Shares, (ii) except as set forth in the Registration Statement
or Prospectus or any documents incorporated by reference therein, seek to
challenge the legality or enforceability of any of the Documents filed, or
required to be filed, as exhibits to the Registration Statement, (iii) except as
set forth in the Registration Statement or Prospectus or any documents
incorporated by reference therein seek damages or other remedies with respect to
any of the Documents filed, or required to be filed, as exhibits to the
Registration Statement except as would not have a Material Adverse Effect, (iv)
except as set forth in or contemplated by the Registration Statement or the
Prospectus or any of the documents incorporated by reference into the
Registration Statement or the Prospectus, seek money damages in excess of 10% of
the current assets of the Company and its subsidiaries on a consolidated basis
or seek to impose criminal penalties upon the Company, any of its Subsidiaries
or any of their respective officers or directors in their capacities as such and
of which such counsel has knowledge, other than ordinary routine litigation
incidental to the Company's business, or (v) except as set forth in or
contemplated by the Registration Statement or the Prospectus or any of the
documents incorporated by reference into the Registration Statement or the
Prospectus, seek to enjoin any of the business activities of the Company or any
of its Subsidiaries or the transactions described in the Prospectus and of which
such counsel has knowledge.

     Such counsel has participated in the preparation of the Registration
Statement and the Prospectus. From time to time in connection therewith such
counsel has had discussions with (i) officers and representatives of the
Company, (ii) representatives of KPMG LLP, the independent accountants who
examined certain of the financial statements of the Company and its consolidated
subsidiaries included or incorporated by reference in the Registration Statement
and the Prospectus, and (iii) the Underwriter's representatives and counsel
concerning the information contained in or incorporated by reference in the
Registration Statement and the Prospectus. Such counsel has not independently
verified and is not passing upon, and does not assume any responsibility for,
the accuracy, completeness or fairness of the information contained in or
incorporated by reference in the Registration Statement and the Prospectus
except to the extent set forth in paragraphs 4 and 7 above. Based solely upon
the participation and discussions described above, however, no facts have come
to such counsel's attention that cause such counsel to believe that the
Registration Statement and the Prospectus, when read collectively (except for
the following as to which such counsel is not called upon to express a view: (a)
financial statements, schedules and other financial data contained in the
Registration Statement or the Prospectus (or incorporated by reference therein)
and (b) the information referred to under the caption "Experts" as having been
included or incorporated by reference into the Registration Statement and the
Prospectus on the authority of KPMG LLP as experts), as of the date thereof or
as of the date hereof, contained or contains any untrue statement of a material
fact or omitted or omits to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances in which they were made, not misleading.

     In rendering the foregoing opinion, counsel may rely, to the extent they
deem such reliance proper, on the opinions of other counsel to the Company as to
matters governed by the laws of jurisdictions other than the United States and
the State of Oklahoma, and as to matters of fact, upon certificates of officers
of the Company and of government officials; provided that such

                                      B-5



counsel shall state that in such counsel's opinion that such counsel and the
Underwriter are justified in relying on such opinions of other counsel. Copies
of all such opinions and certificates shall be furnished to counsel to the
Underwriter on the Closing Date. In connection with the transactions
contemplated by the Agreement and the Transaction Agreement, counsel shall not
be required to opine on, and may expressly exclude from its opinion, any matters
relating to the legal effect of the Public Utility Holding Company Act of 1935
or any related laws, rules or regulations on (1) the conversion of the shares of
Series D Preferred Stock to shares of Common Stock, or (2) the sale, transfer or
delivery of the Shares by the Selling Stockholder or Parent, or (3) the
ownership or other impact arising as a result of such conversion, sale, transfer
or delivery of the Shares. For purposes of paragraph 3 and 13(e) above, such
counsel has reviewed only those statutes, rules and regulations, including
regulatory rules and regulations, that in such counsel's experience are
applicable to transactions of the type contemplated by the Agreement or the
Indenture or for the offering, issuance, sale or delivery of the Shares. For
purposes of the foregoing opinion, the term "knowledge" shall mean the conscious
awareness of information by any Primary Lawyer, without undertaking any
investigation. The term "Primary Lawyer" shall mean each lawyer in such
counsel's Firm who gave substantive attention to representations of the Company
in connection with the transaction described in the Prospectus. Capitalized
terms used in such opinion but not defined shall have the meanings assigned to
them in the Agreement, except the term "Subsidiaries" shall not include any
subsidiaries listed on Schedule II to the Agreement as being organized under the
laws of Mexico ("Excluded Subsidiaries") and counsel shall not be required to
express any opinions regarding any Excluded Subsidiaries.
